Jolt/Tuxedo Pool Member Question
This is the only thread I can find about load balancing JOLT for Oracle Peoplesoft. So I'm going to post what I had to do to get JOLT through the f5, in hopes it will save a little frustration for someone else.
The JOLT protocol uses multiple ports, kinda like passive FTP. The initial connection is on an instance configured port, usually 9200/TCP. Then the server specifies a temporary port for the rest of the conversation, and the client makes a new TCP connecton to that port, often something like 9201, 9202, 9203...
To get it through the f5 LTM, I had to put it on it's own destination IP, and use the "any" port.
ltm pool sc2fi-dev_jolt {

10.1.122.144:any {
